I hate that in WIld Arms 3, you have to be super on-point with starting a particular sidequest otherwise you'll never be able to start it if you accidentally forget to talk to a certain NPC. It's annoying because it's one of the most enjoyable sidequests in the game. >>;
Try doing the true arena in Kirby Star Allies ability-less. Honestly probably the hardest ability-less true arena I've ever gone through. I was really close one time, but I lost due to a mechanic that the final boss's second phase had that I was completely unaware of due to never being ability-less in the actual boss fight
